Sociophysics by Serge Galam

A Physicist's Modeling of Psycho-political Phenomena

Bridging statistical physics and social science, this work presents simple, quantitative models to explain how individual interactions give rise to collective phenomena such as opinion formation, voting outcomes, rumor spreading, extremism, and coalition dynamics. Using concepts like majority-rule updates, contrarians, inflexible minorities, and phase transitions, it shows how small biases and local rules can tip whole societies, producing unexpected results from democratic processes. It blends intuitive explanations with mathematical tools, case studies, and discussion of limits and ethical implications to argue for a predictive, bottom-up science of social behavior.
